安装PostgreSql 这里遇到一个坑,之前装ubuntu的时候,在安装操作系统的时候就选上了一起安装了,但是最后kong运行不起来, 发现官方要求安装的是9.4以上版本,无奈写作9.3重新安装.这里可以参考postgre download

我的操作步骤是:

1. 添加一个非官方源

sudo vim /etc/apt/sources.list.d/pgdg.list
# 添加以下内容
deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main

2. 导入key,刷新

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | \
  sudo apt-key add -
sudo apt-get update

3. 安装postgresql

sudo apt-get install postgresql-9.5

(1).修改配置文件postgresql.conf

sudo vim /etc/postgresql/9.5/main/postgresql.conf

需要修改的内容如下

listen_addresses = '*'
password_encryption = on

(2).修改配置文件pg_hba.conf

sudo vim /etc/postgresql/9.5/main/pg_hba.conf

需要修改的内容如下,尾部加上

host all all 0.0.0.0 0.0.0.0 md5

重启postgresql

sudo service postgresql restart

4. 修改口令

安装过程中,系统已经添加了postgres的用户,并且这个用户的环境变量都设置好了,命令行工具很丰富.

sudo passwd postgres

然后切换到用户,修改postgre数据库的密码

su - postgres

修改密码

postgres@vos2016062102:~$ psql postgres 
psql (9.5.3)
输入 "help" 来获取帮助信息.

postgres=# alter user postgres with password 'your password';
ALTER ROLE
postgres=#

5. 建立数据库给kong用

先创建用户

CREATE USER kong_user WITH PASSWORD 'kong_pass';

创建数据库,并给用户授权

create database "kong_db";

GRANT ALL PRIVILEGES ON DATABASE "kong_db" to kong_user;

至此,数据库准备完毕,当然还有另外一个选择,Apache Cassandra这里就不去介绍了.

安装kong

安装之前先保证如下软件安装

sudo apt-get install netcat openssl libpcre3 dnsmasq procps

在https://getkong.org/install/ubuntu/下载最新的kong的deb安装包,然后

sudo dpkg -i kong-0.8.3.*.deb

配置kong

kong的配置相对简单,我这里只是简单的配置了数据库.

sudo vim /etc/kong/kong.yml

修改数据库配置

######
## Specify which database to use. Only "cassandra" and "postgres" are currently available.
database: postgres

######
## PostgreSQL configuration
postgres:
  host: "127.0.0.1"
  port: 5434

  ######
  ## Name of the database used by Kong. Will be created if it does not exist.
  database: kong_db

  #####
  ## User authentication settings
  user: "kong_user"
  password: "kong_pass"

启动kong
